I mean this is a known thing in general; the best kitchen supply stuff you can buy is often stuff intended for commercial use, because it quite literally goes through the wringer with near-constant usage over long periods of time.

The problem is finding a place that sells commercial things to individual buyers. That, and sometimes what a commercial kitchen needs is vastly oversized for a regular house; you're probably going to set off your residential fire alarm very often with a massive commercial range designed for woks, for example, unless you also upgrade the ventilation, etc.
